This commit adds a TOML configuration option to swarm. It reuses the TOML configuration structure used in geth with swarm customized items. The commit: * Adds a "dumpconfig" command to the swarm executable which allows printing the (default) configuration to stdout, which then can be redirected to a file in order to customize it. * Adds a "--config <file>" option to the swarm executable which will allow to load a configuration file in TOML format from the specified location in order to initialize the Swarm node The override priorities are like follows: environment variables override command line arguments override config file override default config.
